The philosophy of intentionality asks questions such as: in virtue of what does a sentence, picture, or mental state represent that the world is a certain way? The subquestion I focus upon here concerns the semantic properties of language: in virtue of what does a name such as 'London' refer to something or a predicate such as 'is large' apply to some object?This essay examines one kind of answer to this "metasemantic" 1 question: interpretationism, instances of which have been proposed by Donald Davidson, David Lewis, and others. I characterize the "twostep" form common to such approaches and briefl y say how two versions described by David Lewis fi t this pattern. Then I describe a fundamental challenge to this approach: a "permutation argument" that contends, by interpretationist lights, there can be no fact of the matter about lexical

John Hawthorne in a recent paper takes issue with Lewisian accounts of counterfactuals, when relevant laws of nature are chancy. I respond to his arguments on behalf of the Lewisian, and conclude that while some can be rebutted, the case against the original Lewisian account is strong.I develop a neo-Lewisian account of what makes for closeness of worlds. I argue that my revised version avoids Hawthorne's challenges. I argue that this is closer to the spirit of Lewis's first (non-chancy) proposal than is Lewis's own suggested modification.

Although the Evans argument against vague identity has been much discussed, proposals for blocking it have not so far satisfied general conditions which any solution ought to meet. Moreover, the relation between ontically vague identity and ontic vagueness more generally has not yet been satisfactorily addressed. I advocate a way of resisting the Evans argument which satisfies the conditions. To show how this approach can vindicate particular cases of ontically vague identity, I develop a framework for describing ontic vagueness in general in terms of multiple actualities. This provides a principled approach to ontically vague identity which is unaffected by the Evans argument.
